Abstract
On the basis of recorded (Oulu, Finland) high resolution Fourier transform spectra ($\nu_{3}, \nu_{5}$, and $\nu_{6}$ bands) and of ``super-combination differences'' $method^{a} A_{1}-A_{2} (K=3)$ splittings were first time determined in the ground vibrational state of the $^{12}CH_{3}D$ molecule for the states with $10 < J < 22$. Problem of simultaneous determination of the $\bar{\epsilon}$ and $\bar{h}_{3}$ parameters which are responsible for such splittings is solved on the basis both of theoretical calculation and of analysis of resonance interactions in recorded experimental spectra. Numerous peculiarities in the spectra of the $\nu_{3}, \nu_{5}$, and $\nu_{6}$ bands (in particular $A_{1}-A_{2}$ splittings for the $K=1,2,3,4,5,6,7$, and othe effects) are discussed. Analogous problems for the $^{13}CH_{3}D$ molecule are considered.
